Deleting Level Instances

Hi,

I’m using level streaming and Get Streaming Level>Create Instance nodes to generate level tiles in my game. I also want the ability to destroy the streamed level instances but the node Should be Loaded only seems to hide the instances. I saw an answer to this being the following:

In c++ you can use bIsRequestingUnloadAndRemoval flag in ULevelStreaming. Set it to ‘true’ and engine will remove that level streaming object once sub-level is unloaded.

I’m wondering how to access this in c++ or expose it to blueprint somehow.

Thanks,
Jack
